Don't see any reason to ban bascilca personally. Both tarot cards and dispel work as decent counters to it (at least from my experiences with the skill), so it's not like its unstoppable. It has it's uses in terms of strategies and if a team doesn't have the required players to deal with it, they didn't plan properly. Once again, I'm focusing on teams of a decent size. It's just too messy with small teams.
